B nown that I, snn'r D. GRovER, a

tain new and useful'lmprovements in Coin- Controlled Vending-Machines, of. which the is vended-in ism operable y means of a coin of the proper denomination.

The object of my improved vendin 'mech-' anism is to. rovide a delivery -mec anism that will deliver the packages of merchandise one at a time and that will prevent their fraudulent-removal from the machine.

Another object of my invention is to so construct and arrange the various parts of the delivery mechanism and the coin-testing device that they will occupy the smallest possible spacei I In the drawings, Figure 1- represents a rear elevation of my improved vending-machine. Fig. 2 is a sectional elevation of my improved vending-machine through line 2 2, Fig. 1. Fig. 3 is a artial sectional elevation through line 2 2, ig. l,'showing a coin in serted in a coin-slide and the delivery mechanism in the act of delivering a package of merchandise F1g. 4 1s a sectiona elevatlon similar to Fig. 3, showing the delivery mechanism in position where it is deliverin one of the packages ofmerchandise and t e coin being removed from the coin-opening.

In the drawings'representing my improved vending-machinel represents the casing of the machine. I,

2 is the stack, arranged to contain the merchandise to be vended, and 3a weight which serves to move the packages of merchandise downwardto insure their delivery from-the opening 4.-

My coinreceiving'and testing device is comprised of a coin-slide 5, provided with a bearing in thecasing 1 and a round opening 6 of a size to receive a coin of the proper denomination, the coin-opening 7 in the casing, through which the com is inserted into the coin-o ening 6, the frame 8, located over and partia y inclosing the coin-slide 5, which is provided with a projecting lug forming bear m'gs'Q, 10, and 11 for portions of the testin mechanism, and a movable pawl 12, pivote r Specification of Letters Patent.

" the bearing 11 and provided with a point v so formed as to enter a notch 14 'in one edge of the coin-slide 5. The ndtch 14 and the lever 12, serve tolock" the coin-slide manner as to revolve thereon. The shaft 17 with, its outer end being flattened and ing-lug 11 in such mariner that it is free to .move 'sidewise vertically with reference to the coin-slide, so that when the segment 15 is revolved by means of the pinion 19 and the rack-teeth 19. cut in the edge of the coinslide 5, the point 15 will contact with the coin and raise the end of shaft 17 in the slot 1 11} and by its contact with the under side of the pawl 12 raise the point 13 out of contact with the notch in the edge of the coin-slide.

I 18 is a spiral spring wound upon said sleeve 16, one end of which is attached to the segment 15, its other end being secured to the sleeve 16 and arranged to enmesh with therack-teeth 19%, cut in'the'edge of the coinslide 5. V k I 20 is a tilting'lever pivoted in the bearin 20and provided with a spring 2]., Whic normally causes its point -22 to lie upon the top of the coin-slide 5, which is so arranged as to permit said point to enter a slot in one side of the coin-opening 6 to project under and lift the coin out of said coin-opening when 'a package of merchandise has been delivered.

23 represents an outwardly-projecting lug upon the lower end of the coin-slide 5 and is ada ted to receive theend of the pull rod 24.

lug 25, which is attached to the casing of the machine. A spiral spring 26 is inserted between the lugs 23 and in such manner as pulled downwardly by the pull-rod 24.

There is attached to the coin-slide a plate gles thereto and is provided with an angular slot 28 so shaped as to receive the dpoint 29, attachedto the lower end of the goo s-ejector v I 4 m aedi ru 9,1907. Application 1116a December 18,1906. Serial Nb. 292,367; 9

is pivoted at one end in the bearing 9, passes under the-movable pawl 12 in contact there mounted in a slot 1 1%, contained in the bearagainst operation when a. fraudulent money 7 16 is in turn mounted on the shaft 17 in such to a pinion 19, thefpinion 19Iibeing secured I 9 oil Sair pull-rod 24 passes through a slot in the a to be compressed when the coin-slide 5 is 27, which extends downwardly at rightan- 9 ing the machine to be in its normal position,

30, and impart anoscillating movement to it.

Said oods-ejector 30 is attached'to the shaft '31, which in turn is revolubly mounted in the bearings 32 32. i The upper portion of the oods-ejector 30 has the crosspiece"33 so iormed and arranged as to contact with the lowermost of the merchandise packages 34 34 &c., to eject it from the stack 2.

35 isa block which is attached to a spring 36, the lower end of said spring 36 beingat- I tached to the plate 27 by means of a suitable lug 37, the purpose of the spring 36 being to permit the block 35 to move in the opening 28 by contact with the pin 29. The purpose of the block 35 will be hereafter explained.

The lowerpart of the casing 1 serves as a money-receptacle and is provided with the door 38, one edge of'which rests upon the lug 39, the' other being provided with a catch 40, adapted to receive the being end 41 of the rod 42. Said rod 42 extends upwardly 'to the upper end of the machine and has a portion 43 ent at right an les, so as to be inclosed by the catch 44 when 1n its locked osition.

' 45 represents a lock-plate WhlCll is secured in the upper end of the casing 1 by means of the "catch 44, secured therein, which catch passes through an opening 46 in the back plate of the casing 1. The lock-is provided with the usual ke -tumblers and the bolt 47 which passes un er the In 48. The lug 48 is secured to the casing 1 o the machine.

The operation of my improved coin-controlled vending-machine is as follows, assumas shown in sectional elevation, Fig. 2: On placing a coin in the coin-opening 7 and thereafter pulling downwardly upon the pullrod 24 the coin-slide 5 will be moved downward] and the pinion 19 revolved by means of rac -.teeth out in the side of said coin-slide 5 until the point of the segment contacts with the coin'. It will be noted that the distance from the slide 5 to the center of the shaft 17, as indicated in Fig. 4,-is less than the len th of the segment 15 from the center of the s aft to its point, so that when the shaft. 17 is revolved and the point of the segment 15 contacts with the coin in the coin-slot, as indicated in, Fig. 3, and the coin travels downward, revolvin said segment 15 it will raise the shaft 17 in 1ts bearings, and thereby inove the point 13 of the lever 12 outwardly'and out of contact with the notch 14 in the side of the coin-slide, thereby permitting said coinslide to move downwardly, as shown in Fig. 1 3, whereu on the pin 29 will contact with the wall 49 o the angular slot 28 and will oscil-- late the goods-ejector 30, as shown in Fig. 4, and ush outwardly a package ofithe goods; At t e same time the pivoted. lever will eject the coin, so that it will fall downwardly into the bottom of the casing. Upon releasing the ull-rod 24 the coin-slide5 will move upwar y to its normal position, and the pin "29 will ride upon the angular piece 35, as

shown in Fig. 4, andhold the goods-ejector in the position shown in Fig. 4 until the upper end of. the coin-slide 5 moves upward y s to a position to cover the goods-opening'4 in the casing 1,, as shown'in Figs. 2 and 3. The purpose of this movement is to prevent persons from fraudulently pulling out of goods without inserting a coin of t denomination. V

\ The stack or receptacle for holding the 1e proper Ipackages packages to be vended is so constructed as'to e easily removed from the casing 1 when the lock-plate is unlocked and removed and has secured to the bottom the pins 50 50, which are arran ed to enter holes-in the brackets 51 51. tached to the casing 1 of the vending-machine.
